Update from your old 12v sealed lead acid deep cycle battery

Lithium ion batteries are a significant advancement on conventional deep cycle batteries and have led to a revolution in energy storage. Traditionally, when looking for a 12v sealed lead acid deep cycle battery the options were either an absorbed glass mat (or AGM) or a Gel cell.

A sealed battery in in either option can never be totally sealed, as a safety valve needs to be present due to overpressure risks if the battery is overcharged. This is why such batteries are known as valve-regulated batteries. What in fact happens in the battery is that oxygen evolves at the positive point and will mostly recombine with the hydrogen ready to evolve on the negative and thus prevent water loss. The valve exists as a safety feature in case dangerous amounts of hydrogen are produced.

A lithium ion battery, unlike a 12v sealed lead acid deep cycle battery, however remains totally sealed. The premium deep cycle batteries manufactured by Deep Cycle Systems use a proprietary range of DCS 3.2V cyclindrical cells comprising lithium phosphate energy storage which is one of the safest lithium cells available. They offer superior cyclic performance that has been specifically engineered for deep cycle applications.

When failure is not an option, and it’s time to update from a 12v sealed lead acid deep cycle battery look no further than DCS lithium battery from Deep Cycle Systems.
